Richard Armitage is Old Vic at 200 ambassador

Listed here. The program’s description is here, but it’s not clear what if anything Armitage is doing to participate actively.

The Bicentenary Ambassadors will variously curate monologues, appear on stage, share their reflections on the theatre, attend special events around the birthday itself and throughout the year, and help to raise awareness of the education and community programmes that serve 10,000 young people each year.

Confirmed highlights include Maxine Peake curating a series of monologues called One Hand Tied Behind Us to mark International Women’s Day and the 100th anniversary of the Representation of the People Act of 1918; actor Bertie Carvel running the London Marathon to raise much needed funds; Helen McCrory conducting an acting workshop for budding actors or actresses; as well as Ambassadors such as Judi Dench, Ralph Fiennes, Glenda Jackson, David Haig, Jane Horrocks, Tim Key, Joshua McGuire, Rhys Ifans, Daniel Radcliffe and Rufus Sewell sharing birthday messages to the theatre that will be released during the week of the birthday in May.

I’m a little late into this post, but I’m very busy at work, so it’s hard to keep up 🙂
I can’t help but feel this is the theatre RA referred to when he said he would be on stage in London before the summer.
As you say, it’s not entirely clear from this announcement in which function he’ll be appearing or what his contribution may otherwise be.
